INSULA'IJOR-SUPPOBT ron ELECTRIC wines.

To all whom it may concern:

Be it known that I, FRANK P. KOBERT, a citizen of the United States, and residing at New Haven, in the county of New Haven 5 and State of Connecticut, have invented certain new and useful Improvements in Insu-' lator-Supports for ElettrioWires, of whlch the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. 1

ports for electric wires, and particularly to devices of this class designed for use in connection with the cross arms usually employed on electric wire poles or similar supports, and with this and other objects 1n view, the invention consists in a device, or devices of the class specified, constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specificatiDn of which the accompanying drawin forms a part, in which the separate parts 0 my improvement are desig nated by suitable reference characters in each of the views, and in which Figure 1 is a cross sectional view of one of the cross arms used in connection with a pole or similar device, for the purpose of supporting electric wires, and showing my improvement applied thereto with the construction thereof partly in; section ;--Fig. 2 a section on the dine 2-.-2 of Fig; 1;Fig. 3 a section-on the line 3-3 of Fig. 1, and Fig.4 a section on the line 4-4 of Fig. 1.

In the drawing forming part of this specification, I have shown at a one of the cross arms usually employed inv connection with a gale for supporting electric wires, and in e practice of my invention, I pro vide an insulator support for use in connection with said arm, and comprising tr' bottom member b, a top member a, and side members 1!, the top member .a being provided with a vertical pin e with which the insulator f is o connected in the usual or any desired man- The bottom member 1) consists of a piece of channel iron which is ldhger than. the transverse dimensions of the arm a, andthc 1 60 end portions of which open downwardly, as

sho n at 6 and-the top or back of the end Specification of Letters Patent. I n ppl ication filed January 10, 1914. Serial No. 811,315.

- This invention relates to insulator 'sup-' Patented Sept.

l the horizontal central portions of said part b, as shown at b.

The top member 0 consists of a plate which is from two to three inches wide, and which is longer than the transverse dimensions of the arm a, and the end portions of which are bent upwardly, as shown at 0", and said end portions are also provided with central preferably longitudinal slots 0 which are extended into' the horizontal central portion. of said plate, as shown at 0*.

The side members 03 consist of bolts or rods passed upwardly throu h the slots or openmgs b and through t e slots or openings 0, and one end of which, preferably the lower end, is provided with T-heads (Z in the construction shown, but these heads may be spherical in form, if desired, and the other ends of said rods, the upper ends, as shown, are provided with nuts d having convex or semi spherical bottom portions (5*.

This construction, as will be seen, produces a strong and substantial frame which may be securely bound to, or secured to the arm a,'and in the operation of turning the nuts d so as to tighten the bolts 0r rods (Z and bind the to and bottom members of said frame toget er, the bolts or rods all move in wardly and press against the sides of the arm a, and the top and bottom members are also drawn into close connection with the top and bottom of the aim a and this construction also adapts the device to arms of difierent transverse and vertical. dimensions, as will be readily understood.

The pin e is provided with a welded or otherwise formed head e which is riveted to the plate a forming the top member of the frame, as shown at e or said pin may be secured to said plate in any desired manner.

The pin e may be of any dcs'ned length, and the insulator f may be connected'therewith or secured thereto in the usual preferred manner, and changes in an fications of the construction herein describer may be made, within the scope of the appended claims, without departing from. the

spirit of my invention or sacrificing-its ad! vantages.

lot

It will also be understood that any (liesircd' number of bracket frames made in the. manner described may be connected with the arm a, lIIld'WllldlOt 1n any way weaken or injure and two side rods, said side rods being we vided at one end with nuts, and being passed through the end portions of the top and bottom members, said end portions of said top and bottom members being also provided with means whereby the operation of tightening said nuts will tighten the top and bottom members on the top and bottom surfaces of said arm and also draw said rods in close.

contact with the sides of said arm.

2. The herein described means for securing insulators to the arm of a tele raph pole or other support comprising. a rame consisting of a top member, a bottommember and side members, the bottom member ex- I tending transverselyof the bottom of said arm and being longer than the transverse dimensions of said arm, and the end portions thereof bein curved downwardly and provided with longitudinal slots, and the top member extending transversely across the top of said arm and being longer than the transverse dimensions thereof, and the end portions of said top member being curved upwardly and provided with central slots, and the side members consisting of rods passed through the slots in the end portions of said members and provided at one end with heads and at the other end With nuts.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 29th day of December, 1913; a V FRANK P. KOBERT.
